Gravity Q and A with Professor Brian Cox

"I think it is a perfect description of space - The only way to get a more realistic depiction of space would be actually to go into space"

In this special screening question and answer session, Mark Salisbury introduces Professor Brian Cox and VFX Supervisor Tim Webber to lead a discussion around Gravity

Taking 4 1/2 years to make (with 3 years in production), they had to invent some of the filmmaking techniques as they went along

As discussed in the clip, space debris is a real threat:
"The energy that even small flecks of paint have in orbit means they are like bullets and can cause serious damage. A piece of debris as big as a hand can take out a space shuttle."

With the knowledge that this scenario may well be one which we will face in the future, what are your thoughts about the film? And the possibility of this situation arising?
